CONVEYING MECHAN'ISM.

To all whom t may concern.'

Be it known that I, JOSEPH FREUD, c1t1-v zen of the United States, residing at Chivantages. The mechanism of my invention cago, in the county of Cookand State of Illinois, have invented a certam new and y useful Improvement in Conveyin Mechanism, of which the following is a ull, clear,v

concise, and exact description.v i

My invention relates to conveying mecha'-r nism and has a'number of objects and adl is particularly adapted to the transfer of Hedges of the feeding bottles to boxes in which they are' to be packed although other articles than bottles may be transferred by-means of my invention..

In accordance with one feature of myrfinvention there is a belt or other support for feeding 'the bottles or other articles to the machine and another belt or belts having stretches which margin the longitudinal belt to engage. the

- bottles or other articles upon the feeding any bottle s belt and position them thereupon.

Means are also desirably employed for checking the travelof the feeding belt or` Support and which lmeans is operable by an article when abnormally positionedy upon bottles upri ht upon the feeding belt but if ould fall flat upon the belt the machinev will 4be stopped by means of this part of my invention. 1 A The machine -ofJ myinvention also desirably includes two angularly related belts l or supports,` one of thesebelts'being the feeding belt' lhitherto mentioned and the second a belt upon which vows of articles are assembled and which rows are placed uponthe second belt one by one by being pushed laterally -from the feeding belt'. employed bottles `01," other articles is assembled to form each row.

Suitable counting mechanism is whereby la definite number of upon the feeding belt before such row is transferred to the second belt whereafter -the second belt is. operated by the counting 'mechanism to effect the' travel of the rows of bottles vthereupon and to place a new portion thereofin position to receive va fresh row of bottles. The mechanism for moving group ofrelatively movable wedging pushers that serve to spread the bottles apart' to provide placestherebetween that correspond PSpecication q'f Letters Patent. I

`that the rows of bottles are yIt is desirable to place thetlesby machinery into the .feeding belt to the second belt and the ste by step movement ofthe second belt is suc alpart corresponding to the spaces between t ese rows tha is to occur when the bottles are boxed. l 1 The belt that is second to receive the bottles is -desirably provided with bottle positioning pins and swinging' arms for holding the bottles -in engav ement with .positioning pins.' These posi ioningpis and arms are desirably lwithdrawn when not functioning. A

After a complement lof rows of bottles has been collected upon the 'second conveying belt or support, clutching mechanism is lowered into engagement with the necks of the bottles and after this clutching mechanism has gripped 'the bottles such mechanism is transferred, together with, the bottles gripped thereby, to position the bottles over the 'box that is to contain them whereafter, the clutching mechanism and the bottles are lowered `-to deposit the bottles into the box whereupon `the clutches are released and ithdrawn to their initial position over the second belt. -There are some boxes. which carry handles inside of theboxes and which handles' partially cover some'pockets in the boxes that are to receive bottles.' These handles would interfere withthe deposit of' botcovered by the handles. I `therefore rovide.- means for shortening, the `rows of ot- `tles that occur whene the handles are lolcated,` thisA function being desi-rably per?v formed byjpushing someof the.K bottles colf the 'first or feeding belt from lected upon this belt onto a \recei'ving platform from whichthey are removed by an attendant by` the box haning the operation Patented Feb. 10, 1920. `Application led December 26, 1917.

In the foregoing preamble I have frequently'referred specifically to bottles as' bewho deposits them inv thev ockets in theibox that are partially covere dles. 'bottles boxes and which broken bottles 'shouldbe` removed before newbottles are boxed. I Vprovide means for check the bottles from the feedingr belt'onto the second belt is desirably in thenature of al vention is not to be limited.

'ing the articles up'on which the mechanism operates but it 'is to be understood that my invention is not to be limited to the nature ofthe articles operated upon. )There are other features and advantages of my invention which will fully appear and which, together with the foregoing objects of my invention are desirably realized by the mechanism hitherto generally described but to the specific details of which mechanism my in- I will explain. my invention more fully by reference to the accompanying drawings showing` the preferred embodiment thereof and in which Figure 1 is a plan view of the machine constructed inaccordance 'with the preferred embodiment of the invention; Fig. 2 is one side elevation of the machine; Fig. 3 is another side elevation of the machine; Figs. 4 and 5, taken collectively and read with the right hand end of.

Like parts are indi-cated bysimilar char-` acters of reference 'throughout the different gures. l A

The feeding or conveying mechanism, 'by means whereof the bottles 1 or other articles are fed to the machine, is inclusive of Ia 26 is' a .view on the outermost end of the upper stretch of the traveling belt 2 and are maintained in their upright positions in the initial portion of the travel of the bottles by means of the inner stretches of the symmetrically arranged traveling belts 3 and the inner stretches' of the symmetrically arranged traveling belts 4, these belts 3,.4 margining the longitudinal edges of the belt 2 and being driven by gearing later to be set forth. The belts 4 are located to engage the bottles below the labels thereon that may be wet if they have been freshly applied to the bottles, while the belts 3 are located to engage the bottles above the labels thereon whereby the belts 3, 4 are prevented from marring the labels. The bottles arecari'ied by the belt '2 beyond the belts 3,4and enter between the inner stretches of the traveling belts 5 (driven by gearing to be laterset forth) that margin onelongitudinal edge of the belt 2 and a roller 6 at the opposite edge of the belt 2 and which roller is carried upon one arm of a bell crank 7 that is movable horizontally. The roller 6.occupies a level between the belts 3 and 4 and is in the ,plane of the horizontal diameter of any bottle that may have been accidentally turned to a horizontal position to lie flat upon the feeding upper stretch of the belt 2, Fig. 10. A spring 8 operates upon the bell crank 7 to hold the roller 6 in the path of movement of the bottles so that as each bottle encounters the roller -6 such roller is. pressed outwardly to cause counter-clockwise movement of the bell crank 7 (Fig. 22). rlhe duration of engagement of each upright bottle with the roller 6 is so short as` to occasion no operating change in the mechanism but if thebottle engagingsaid roller has accidentally been laid fiat upon the belt 2 (as shown by-the dot and dash circle in'Fig, 10) the duration of engagement of the'bottle with said roller is suliciently extended to" bell crank 9, that is movable vertically, when l the bell crank 7 is moved counterclockvvise. The bell crank Q has pin and groove connec- Vtion with a' clutch member 10 that is splined engagement between the roller 6 and a bottle lying Hat upon the belt 2 will cause and maintain operating engagement between the clutch members 10 and 12 to` cause the clutch member 12 to rotate with the motor driven shaft 11. The clutch member 12 is in actuating relation with the fly ball switch actua't.- ing mechanism 13 and when this clutch member 12 is rotated the switch actuating mechanism 13 will operate to moVe the con-v tact 14 against the contact 15 to include the solenoid or other electro-ma et 16 in circuit with a source of current 1 Fig. 28. The magnet 16, when energized, serves to dissociate the machine operating prime mover from the machine.

In the preferred embodiment ofthe invention the prime mover is an electric-motor 18, in which event the magnet- 16 serves, when energized, tolseparate the contacts of the switch 19 that is serially included in cirl cuit between the motor 18 land the generator 17. The machine will vstop while a bottle lying fiat upona belt` 2- is in engagement with the roller 6.

In addition to opening the circuit of the motor the energized magnet 16 also desirably effectsor permits the application of a brake quickly to stop the operation of the machine. This brake includes a brake band 20 surrounding a brake pulley 201 that is fixed upon the shaft 21 which is driven by a pulley 22, which is turned by a belt 23 driven by the motor 18Figs. 2` and 24. The brake band has outsetting ears 202 that are thread. ed by a bolt 203. A projecting end of this bolt is surrounded by acoiled spring -20 which is prevented from or is-permitted-to force the ears 202 toward each other to apply the brake band to the brake pulley 201. The lever 24, pivoted-at its lower end, is operated by the magnet 16 and carries one ofl the'co'ntacts of the switch 19. This leven carries an extension 25 that serves to hold the brake band expanding links 26 in alinement 'when the magnet 16 is ,not energized, at which .v time the spring 204 is prevented from appllying'tlie brake band -2Qtol the brake pu ey 201'. When the magnet 16 is energized the' lever 24. is moved to a position in which the links' 26 are thrownI out of`alinement whereupo'ngthev-spring 20* is free to apply the brake band. J

When the attendant. rights the bottle the spring 8 assuming that .the bottle has propcrank-.7 and cause the separation of theI 16 and permit the closure of the switch 19 by the sprin 27 and the consequent estabL lishment of t e operating circuit of the motor 18.4 After the bottles clear the belts 5 they enter between thew inner stretches of the .symmetricallyarranged belts 28 (driven by the motor through the intermediation of gearing later to be set forth) and' the inner.

stretches of the symmetrically varranged belts 29 the inner stretches of these belts margining the longitudinal 'edges of the belt 2. The belts 28 are in the same horizontal plane with the belts 3 and the belts 29 are in the same horizontal plane with the belts 4 to clear the labels upon the bottles As each bottle lis about to passl from vbetween the belts 28 and the belts 29 it encounters a roller 3() u on a bell crank31 whereby this bell crank) is movedagainst the force of spring 3.2 to close the contacts of switch 33.` This switch is in serial relation with the solenoid or other electro-magnet 34 and the generator 17 and serves to establish a circuit for said V magnet each time a bottle engages the roller packed in a box. The ratchetwheel 351 has twenty-four teeth and is to be employed when twenty-four bottles are to be packed in a box. 'The employed ratchet wheel is operated step by step as the bottles successively a engage the roller 30 and when a full complement of bottles has been passed'to the ma ste by step, a complete revolution.

' chine the employed wheel 35 or 351 is turned, y

n the same shaft 35'2 with the counting are operated when the wheel 35 is employed and two star wheels 361,371 which are oper#v ated When'the wheel 351 is employed. The shaft 352- that carries allof .these wheels is v .wheels 35 351y are two star wheels 36,37 that .adjustable longitudinally of. itselfV in order y to bring one o r the other of the wheels 35,

351 into coperative relation' withl the mag- Inet 34. Further operation .of the machine` .v will be describedl as though the wheels 35, 36`

and 37 are employed. .l .7 'I l The. wheel 37 (also the wheel 371) ihas six equidistant teeth p'rojecting-'from` its periph.-

ery-which are brought `successively into en-v gagement with the lpin 38 upon the upperN end of a rocking leven 3 9. This en ment happens each time aerow of bott es is placed upon the belt 2 and is for the -purpose of setting machinery `into operation-` ge' i that -will move each row of bottles laterally:y

of the belt 2 unto the upper stretch of a" erly cleared the roller 6) will restore the bell lever 39 with one end of the link 41.

other `end of the link 41 is connected with a yare transferred from the belt 40 to the'boX being hereinafter set forth.

A link 41 is disposed transversely of the lever 39 and has slidinor connection therewith. A spring 42 yieldingly connects Itlle e clutch lever 43 which is pivoted at 44. This clutch lever is in pin and groove connection with a. clutch member 45 that has splined connection with a constantly rotatingmotor driven shaft 46 (driven by the gearing 461,

462 and 463 intervening between the shafts 21 and'46). The spring 47, when free to operate, moves the clutch member 45 to the left to separate it from a complemental clutch member 48 that is loose upon the sha-ft 46. The wheels 35 etc. (Fig. 11) turn counter-clockwise and each time a tooth ulpon the star wheel 37 strikes the pin 38 the lever 39 is turned clockwise and operates thronghrthe spring 42 to turn the clutch lever 33 clockwise to bring the clutch meub ber 45 into engagement with the clutch member 48. The clutch lever 43 carries a latch 49 that is caught by a catch 50 when this clutch lever 43 is moved to engage the clutch member 45`witl1 the clutch member 48, the elements 49, 50 maintaining the clutch members 45, 48 in engagement until the shaft 4.6 has made one revolution, the shaft then Y bringing the calm 5l into engagement with the tail of the catch to disengage this catch from the latch 49 whereupon the spring 47 will separate the clutch members 45, 48 to the extent permitted by the lever 39 and the star wheel 37. Such a v*complete revolution of the motor driven shaft 46 occurs for each sixth revolution of the wheel 37 and during such revolution of the shaft 46 the row of bottles. that have been vcollected upon the belt 2 is moved unto the upper stretch of the belt 40. When the clutch members 45 and 48 are in engagement the intermeshed bevel pinions 52 and 53 are driven, the pinion 52 being fixed upon the clutch member 48. The bevel pinion 53 is fixed upon a shaft 54 (Figs. 4, 11 and 27.). A cam 55 is fixed upon the shaft 54 and is engaged by a pin 56 which is upon one end of an intermediately pivoted lever 57, the pin 56 being maintainedv in engagement with the cam by a spring 58. The part of the lever 57 to the left of the lever pivot 571 is bifurcated, thev outer ends of the bifurcations of this lever loosely carrying a'gate 59 that maro'ins the portion of the belt 2 that is moving between the side members -60 of the frame of the machine.v This gate is maintained in any elevated position while a row ofbottles is being collected lupon the belt 2 and after such row of bottles has been collected the gate 59 is dropped sufliciently to bring its upper edge Ainto the plane of the upper stretch of the belt 2 or a little below such plane, a result which is accomplished by the engagement of the rise of the cam 55 with the pin 56. The engagement of the pin 56 with the rise of the caim 55 is maintained during the time that the collected row of bottles is being moved to the left (Fig. 8) from the belt 2 upon the conveyer belt 40. After the transfer of the row of bottles to said belt has been effected` the rise of the cam 55 is passed outof engagement with the pin 56 whereupon the sprmg 58 will again elevate the gate 59 to keep the bottles of the succeeding row that are being collected in alinement upon the belt 2.

When the gate 'has been lowered the wedging pushers 61, 62, 63, 64 and 65 are moved to the left (Fig. 8) to enter between the bottles of the row that is to be pushed upon the conveyer belt 40. The Iirst bottle of the row engages the stop 66 and the succeeding bottles of the row are successively in contact. The apex of the first wedging pusher 61A is more than the diameter of a bottle away from the stop 66 and the apices of each two adjacent wedging'pushers are separated more than the diameter of a bottle.

When the wedging pushers are moved against the 'bottles the bottles are separated -by spaces that slightly exceed the width of the partitions 67 in the box 6 8 so thatfsuch partitions may enter between the bottles. The bottles arepushed by the pushers 61, etc., against the pins 69 upon the conveyer belt '40. lBy means later to be described, after the row of bottles has'been placed upon the conveyer belt such belt is advanced one step in position to bhave anotherportion thereof in position to receive a succeeding row of bottles which are positioned against other pins 69. These pins 69 serve to position the 'bottles with spaces therebetween to receive the partitions 70 in the box 68. The

parallel partitions 67 are at right angles to the parallel partitions 70 and form there--- with rows of bottle receiving spaces A, B, C, D, E and F.

The aforesaid w`edging pushers are hinged upon an angular carrier bar 71, springs 72 holding the apices of ythe wedging pushers in -proper initial. position with respect to lthe bottles and permitting the wedging intermediation of the pitman 80, e ects a arallel to the direction in which a' row'of ottles 74 are to be bodily moved from the belt 2 upon the belt 40, guide the'wedging pushers in such direction in order that they 5 may perform their function. The crossheads that'movesin the slideway4 82. The block 81 carrles a pin 83 that is received in the slot formed in the arm 84.l The arm 84 is fixed u on the lower end of a shaft 85 that is rigi ly connected at-its upper end with 4the aforesaid link 79. vThe'cam 55, throu h the crank movementthat causes the reciprocation of the block or crosshead 81 to cause the to and fro movement of the yoke 76 and thecrossheads 74 with the results that have been described. An arm 86 is anchored at one end to the yoke 76. A member 87.0f an overrunning clutch -is journaled upon-the other end of the'arm 86. `A toothed ring 88, conl stitutinganother member'of said overrun- 1 ning clutch, surrounds and is -carried 'by themem-ber 87 and is adapted to turn with re-'fI spect thereto or is adapted to turn therewith according to theI direction of rotation of 35 said ring. Clutch rollers 89arev interposed between the members 87 and 88 that' cause these two members to turn together when the member 88 turns counterclockwise but when-the .member 88 turns clockwise it is member 87. The member 88 is in mesh with the rack 90 extending-parallel to'thedirection in which the bottles are movable from the belt 2 upon the belt 40. When the wedging pushers are moving the bottles 'from the belt 2 upon the belt 40 the toothed ring 88 is `turned in a clockwise direction because of its engagement with the rack 90, -at which vtime said member 88 turns upon. and with respect to the' member 87. When' the wedging pushers are-being withdrawn the. member 88 is turned in a counter clockwise direction to cause'the member 87 to turn there-v with. The member 87 is also in the nature 55 of a crank, being connected by means of a pitman 91 with an arm 92 rigidly secured lto the shaft 73 to which .the carrier bar .71 is also rigidly secured. By means of the crank vaction efectedfby the clutch member 87 upon the withdrawing movement of the wedging pushers the carrier'bar 71 is turned so aste b e above the tops ofthe bottles of thenext frow that is being collected upony the `belt- 2 wherebfy the wedg'ing pushers clear the '65 bottles .T0 .Such succeeding IOW Whn the box is to contain thirty-six bottles. Each of `quota of six bottles, these last two rows of bottles being lreceived in the rows of spaces upper portion of the shaft 96. A spur gear 98 v adapted toturn upon and with'respect to the p carries the pulleys 111.y that drive the belts' wed-ging pushers arebeing restored to normal position. After the wedging pushers have cleared the bottles they are lowered into their initial position in readiness to remove the succeedingrow of 'bottles from the belt 2 in a manner which has been described.

Some boxes that are to be filled with botl tles may have insetting handles such as those indicated at 93, Fig. 29. These handles would interfere with the automatic deposit of the rows of bottles into the bo'x when boxes having such handles are to b e filled. By mechanism later to A be described', the four bottle spaces at these two handles have to be supplied with bottles by hand., The I first two rows of bottles which are to fill the rows of spaces A, B in the box (Fig. 29) contain, each, six bottles, assuming that the the third and fourth rows of'bottles is minus a bottle at each end and, therefore, contains but fourbottles. The third and fourth rows 4o'f bottles are to be deposited in the rows of l spaces C, D in the box. Each ofthe fifth '90 and sixth rows of bottles is to have the full E, F in the box.

1A bevel gear 94 (Fig. 11) is fixed upon the V9.5-

lshaft 46 and is in mesh with a bevel pinion fixed upon the lower end'of an upright f shaft 96. The rollers 97 that drive the left hand belts 28 (Fig. 22) are fixed upon the is also fixed upon the shaft 96, this spur gear being employed in operating the mechanism that yremoves bottles from the belt 2 that are not, to be placed upon the 'belt 40-but as this spur gear also actuates the operating gearing of other mechanism hitherto described the relation of this spur gear to such other gearing will first be set forth., The spur gear 98 is in mesh with a spur gear 99 thatis fixed upon a shaft 100 upon which the 110 pulleys 101 (that drive the right hand beltsv 28 shown in Fig. 22) are fixed. The spur gear 99 is in mesh with a spurpinion 102 which in turn `is in meshv with a spur gear 103 that is fixed upon the shaft 104 which A carries the pulleys 105 that drive the belts'5.' p ,l The spur gear 103 is in mesh with aspur gear- -106 which, inturn, is in mesh with the pinf ion 107 fixed upon the lower end ofthe shaft 11 (Fig. 10) whereby vthis shaft 1s drlven. 120 The spur geari'103 isal'so in mesh wlth the. spur pinion 108 that, in'turn, 1s'1n meshv wlth `a spur gear 109 fixed upon the shaft110 that and-4 upon the rlght of the belt 2.
